Title: Brake accelerating device operating in a pulsating manner for an indirectly acting compressed air brake for rail vehicles
Inventor: HINTNER JOSEF
IPC: B60T15/42
Filed: 1983-03-25
Abstract: A brake accelerating device operating in a pulsating manner for an indirectly acting compressed air brake for rail vehicles has a pulsator (12) which is connected to the brake line (BP) by way of a nozzle (23). The pulsator (12) forms a combined pressure from two pressures. The one pressure is derived by way of the nozzle (23) from the pressure of the brake line (BP) and the second pressure by way of a further nozzle from the pressure of a control chamber (QAC). At each brake stage the pulsator (12) draws off synchronised combined pressure pulses to the atmosphere, the brake line pressure and the control chamber pressure being simultaneously reduced by way of the combined pressure pulsator (12). The combined pressure may comprise two valves (14, 15). The control element (4) of the brake accelerator unit may be the emergency brake piston which monitors a plurality of valves, of which one valve is the pulsator energising valve (8). <IMAGE>

Title: Method and device for position control of the tool of an edge-grinding machine for glass panes
Inventor: HALBERSCHMIDT FRIEDRICH DIPL I
IPC: B24B9/10
Filed: 1983-04-11
Abstract: In a method for path control of the grinding head of a peripheral-edge-grinding machine for glass panes, in which the glass pane rotates and the grinding head is forced to move along the contour of the glass pane in the direction of the rotation axis of the glass pane, a sensor roller, also displaceable in the direction of the rotation axis of the glass pane, is provided in order to carry out the position control of the grinding head. The path signals determined by the sensor roller are stored in a shift register. After the shift register has been scanned within the time span which corresponds to the rotation angle ( alpha ,  beta ) between the contact point of the sensor member and the contact point of the grinding head with the grinding disc, the signals originating from the shift register are used for the position control of the grinding head. In one embodiment, the sensor roller (11) and the grinding tool (6) are arranged each on a linearly displaceable slideway (12, 7, respectively). According to another embodiment (Fig. 4), the sensor roller (65) and the grinding tool (56) are each arranged at the end of a link (oscillating crank) (63, 57, respectively) and move on a circular orbit. <IMAGE>

Title: Method for monitoring keyboards in digital telecommunication terminals
Inventor: ZEITRAEG ROLF DIPL PHYS
IPC: H03M11/20
Filed: 1983-06-28
Abstract: The invention relates to a method for monitoring keyboards in digital line-fed terminals for key pressure. Keys arranged in columns and rows are monitored by applying a test potential row by row and testing for existing potential column by column. The object of the invention consists in carrying out the monitoring in the idle state with a minimum of energy. This object is achieved by the device sending out the test potential being switched inactive in the idle state, all rows being connected to 0-potential via a switching section controllable by a flip flop and all columns additionally being connected to the inputs of a common NAND gate for setting up the potential test and, on key actuation, the 0-potential of the corresponding row passing via the NAND gate to the flip flop, disconnects the 0-potential from all rows and switches on the device sending out the test potential. Thus, the active energy-consuming keyboard monitoring arrangement is only switched on during the keyboard operating time.

Title: Adjusting device for the blocking dog of the pivoting latch especially on electromagnetically actuable door openers
Inventor: LUETTGENS DIETRICH
IPC: E05B47/04
Filed: 1983-07-15
Abstract: Devices for the adjustment of the entire opener housing on its cover plate and of the blocking dog on its rotary latch by means of toothed plates and clamping screws in long holes are known. There is often insufficient space in the frame to adjust the entire housing, especially in metal door frames, and the tooth steps allow only an approximate setting and an unreliable fastening with screws in long holes. The present invention improves these disadvantages by arranging a slide guide between the plates of the dog and the rotary latch, avoiding the need for clamping screws in long holes. For fine adjustment, there is, according to the invention, a setscrew which is arranged between the setting faces and is rotatable from the end face of the dog by means of a tool and which is guided in a plate transversely to the axis and, by engaging into a nut thread, makes the dog adjustable. Transversely or longitudinally arranged grub screws serve as an additional safeguard for the setting.

Patent DE-3445290-A1 (DE)
Inventor: ADOLF HERBERT
IPC: B29C69/00
Filed: 1984-12-12
Abstract: The process and the appropriate apparatus for producing rigid foam elements, in particular of polyurethane, operate with a double-belt unit, in which the rigid foam elements produced are provided with upper and lower cover sheets. A parting agent is applied on the lower cover sheet in a particular region in order to permit subsequent removal of the upper cover sheet and the ridge foam in this region, so that the lower cover sheet projects, and foams an overlapping section during subsequent use as a roofing element or the like. The invention permits a very precise cut to be made by means of the sawing apparatus at the end of the double-belt unit, taking into account the application of parting agent at the beginning and, if necessary, the movement of the sawing apparatus itself. This is carried out in principle by a method in which the position at which the parting agent is applied, and the path covered after this application, are input into a computer, which initiates the specified transverse cut after the section provided with parting agent has reached the transverse cut position. When the sawing apparatus itself is movable relative to the foam strand, an additional signal relating to this movement is input into the computer and is also taken into account in the initiation of a transverse cut. The electrical signals for the path covered and, where relevant, the movement of the sawing apparatus are generated by meters, meter for the path advantageously being connected to a tail shaft of the double-belt unit.

Title: Process for precipitating dust with simultaneous reduction in NOx and SO2, preferably downstream of coal-fired power stations
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/86
Filed: 1984-12-21
Abstract: It has been proposed to use ceramicising supports for the preparation of catalysts. The catalyst body consists of flotation wastes arising during coal-washing in coal mining as a waste product, 2-10% of coal dust also being additionally admixed to the flotation waste in order to improve the porosity of the catalyst body. It has now been found according to the invention that the addition of coal dust to the ceramicising flotation wastes can be increased to such an extent that a porous body can be produced which is outstandingly suitable for making filter candles for precipitating dust, with a simultaneous catalyst activity. According to the invention, it is therefore proposed that washing wastes and/or flotation wastes are moulded by admixture of coal dust and/or sodium metasilicate to give filter candles or filtration plates or filtration bodies, and ceramicised.
